Over a century ago, in 1839, German scientist Christian Friedrich Schönbein published the principles of a working fuel cell in the January edition of the “Philosophical Magazine” . Inspired by these findings, Sir William Robert Grove, a Welsh scientist, went on to produce the first working fuel cell just four years later in 1843 . Since then, scientists and inventors have been finding new and alternative methods to solving current energy efficiency problems . The first commercial manufacturer of fuel cells, the United Technologies Corporation, has produced fuel cells that supply power to automobiles, buses, cell phone towers, and even space vehicles used in the Apollo missions . Even with all of the leaps and bounds that fuel cell technology has made, there is still room for improvement and even cellular phone firms are attempting to utilize fuel cells in ways that were once thought to be impossible . But in order to understand why a robust power supply is so important to the implementation of a wireless strategy, the current technologies and wireless strategies must first be examined . Quite frankly, any organization that wants to move towards a wireless/mobile network must find some way to provide power for their mobile devices . These could be cell phones, PDA’s, laptops, as well as many other handheld applications . The largest problem with mobile devices is that they must be recharged, typically by a power supply connected to an electrical outlet . Having to do so limits the range of such items, making users of these technologies grounded to a certain spot . This, of course, is the largest concern and biggest difference from a typical wired, immobile network . The goal of any wireless plan is that it behaves as efficiently and effectively as non-wireless, the only

difference being that it works from any location if an individual so desires . Obstacles like these are being made easier to overcome with emerging technologies that go leaps and bounds above what is currently available to the consumer . The power supply market is restricted by the rechargeable batteries that are used in such wireless devices as the Apple iPhone, a mobile phone that must be attached to a power supply which plugs into a wall socket in order for it to operate . By forcing the user of the device to use a grounded power supply, the mobility of the device is weakened . However, emerging technology firms like Medis Technologies are developing mobile power supplies, disposable fuel cells that can provide 30 hours of mobile charging ability . By being both lightweight and disposable, the new fuel cells extend the range of any device they are applied to . Medis Technologies is researching and producing fuel cells for laptop computers as well,
